Flow sensor (for liquids) RFO series, pulse output for liquid flow and visual confirmation, 4.5 to 24 Vdc pulse output. Manufactured by Gems.
The flow sensor features a liquid rotor with an outer wheel design, where the rotor and electronics can be visually inspected and are packaged within a compact, panel-mountable housing. It provides an accurate flow rate as an electrical output, allows for visual confirmation of flow, and is economical. Typical flow sensor applications include: - Water purification and water distribution systems - Chemical dosing devices and semiconductor processing equipment - Testing of water injection systems and water delivery systems - Ensuring appropriate processing, mixing, and distribution operations in laser and welding equipment, coolers, and heat exchangers. Signal output: The voltage output of the flow sensor RFO type is an on/off pulse of the DC voltage supplied to the unit. The input voltage range is from 4.5 to 24Vdc, making it easily compatible with digital logic circuits. The frequency of the output pulse is proportional to the flow rate, ranging from approximately 15Hz at low flow to about 225Hz at high flow.
